People leaving might look to you as "more and more people worrying", but in reality the numbers don't show that. It's just your observation bias that is telling you what you want to believe.
On Reddit, this kind of situation on a subreddit is called a "circlejerk".
I'm aware that I may have biases and that my social group is not representative but do you have these numbers you are speaking about? Because you seem sure about this so I'd appreciate to be taught against my biases.
Until that, I'll stay with the idea that much more people are at least aware of issues around new tech today than before Snowden revelations, let alone the beginning of the 2000s, and some of them are not happy with this even if they haven't taken actual actions, and even if they are not the majority.
HN is probably only in advance on those topics compared to the general population by the way.
(I added a clarification to the original post because I'm not sure you understood my post like I intended and the sentence was indeed ambiguous)
